1500W axial Zener TVS for 22V rail clamping
It clamps a 22V reverse standoff rail with a minimum breakdown voltage of 25.9V and a maximum clamping voltage of 37.5V at rated peak pulse current.
onsemi lists the 1N6379 as Obsolete. Sourcing now runs through independent distribution — any available stock should be date-code verified against the original onsemi production period. The DO-201AD axial package is through-hole, which simplifies manual replacement but limits automated assembly throughput.
Design-in note for replacement selection
A direct replacement must match the 1500W peak pulse rating, 22V standoff, and unipolar clamping characteristic in DO-201AD or equivalent axial footprint. The 25.9V breakdown minimum and 37.5V clamping maximum define the protection window — any substitute must hold these thresholds to avoid overvoltage stress on the downstream circuitry.
